CHANNELER.

Application filed March 25, '1922. Serial No. 546,921.

My invention relates to channelers and more particularly to means forcontrolling the feeding of channeling mechanisms of the multiplestandard type.

An object of my invention is to provide an improved channelingmechanism. Another object of my invention is to provide an improvedchanneling mechanism of the multiple standard, multiple-tool type inwhich the channeling devices on either standardmay be controlledindependently of those on the other, or in which both may be readilycontrolled simultaneously, the control mechanism being of an improvednature whereby it is readily accessible from different positions andreadily controllable by the operator. Other objects and advantages of myinvent-ion will hereinafter more fully appear.

In the accompanying drawings, I have shown for purposes of illustrationone form which my invention may assumein practice.

In these drawings,-

Fig. 1 is a view mainly in end elevation,

. but with parts broken away to show details of construction.

Fig. 2 is an enlar ed detail View showing parts as cut on t c sectionline 22 of Fig. 3

Fig. 3 is a plan view of a portion of the channeling mechanism, partsbeing broken away above the section line 3-3 of Fig. 1.

Fig. 4 is section on the line 4-4 of Fig. 1.

Fig. 5. is a view approximately .on the line 55 of Fig. 3, but with mostof the operating mechanism shown in elevation in stead of in section. i

The improved channeling mechanism which constitutes the illustrativeembodiment of my inventionincludes a main frame 1 which is supportednponwheels 2 mounted on axles'3 extending across the frame at oppositeendsthereof. The machine is adapted to be. fed by means of transmissionmechanism generally indicated by 4 driven as desired by the operator bya reversible motor 5 under the control of suitable control mechanism 6,7. As my invention relates more particularly to the means forcontrolling the raising and lowering of the channeling device and to thegeneral arrangement of the parts, the mechanism so far described willnot be more fully set forth. .7

Extending longitudinally of the frame 1 is a bar 8 upon which there areadjustably clamped as at 9 (Fig. 1) standards 10, which standards formguiding means for channeler mechanisms generally indicated by 11. Thesechanneler mechanisms include motors 12 driving, by a suitable gearing ofwhich a portion is shown at 13, a suitable crank shaft 14 which by itsrotation reciprocates a cylin 'der 15 in which a piston 16 connected bya rod 17 to a suitable gang 18 is mounted, the cylinder 15 and gang 18being suitably guided by means carried in the standards 10. Thechanneling mechanisms are each supported on frames 19 andv by feedingthe frames up and down the standards, the tools may be withdrawn orlowered with respect to the bottom of the cut as may be necessary. Afeed screw 20 suitably sup.- ported by a thrust bearing 21 is carriednear the base of the guides on the standards 10, a

this feed screw being rotated by a worm wheel 22 keyed thereto, whichworm wheel is driven by a worm 23 which is in turn driven by'a chain 24and mechanism later more fully described. The feed screw 20 engages witha nut 25 secured on the frame 19 and rotation of the screw 20 will causethe channeling mechanism to move upward or downward in the standardsdependent upon the direction of rotation of the screw 20. It will beunderstood that each of the Y channeling mechanisms cooperating with thestandards is provided with one of'these feed screws and, as will beobserved from Fig. 3, the driving chains QtlrfOI' the worms 23 passaround drivingsprockets 26 and 27 which are secured by split collars .28to sleeves 29 and 30, respectively, which sleeves are journaled uponopposite ends of 'a shaft 31 which is provided with a jou'rnalasindicated .at 32, the sleeves also being journaled exteriorly inbearings 33 and 34 fixed to the frame 1. The shaft 31 carries keyedthereto a beveled gear 85 which is driven by a beveled pinion 36mountedon the opposite end of the armature shaft of the motor 5 fromthat which'drives the truck propelling mechanism. There are also keyedto the shaft 31 a pair of sleeve members 37 and 38, which members areprovided with braking surfaces 39. Carried by the sleeve members 29 and30'are' clutch carrying members 40 of wellknown commercial construction,these including clutchbands 41 which may be tightened by oscillation ofand to one side, and above, the shaft 31, longitudinally movableoperating slide rods 48 and 49, these being provided with shippers 50and 51, respectively, operative to move the cams 44 and 45, and theslide rods 48 and 49 are provided with laterally projecting studs 52 and53 whereby they may be engaged and moved by means which will now bedescribed. It should first be noted, however, that movemets of the rods48 and 49 in opposite directions will cause them to efiect similarfunctions, i. e., relatively opposite movements of the rods will producesimultaneous application of the brake bands 39 and simultaneous releasethereof.

Fixed to the frame are suitable hangers 54 and 55, there being journaledin the hanger 54 a hollow shaft member 56 which carries at one endthereof a socket member 5? and at the opposite end thereof a secondsocket member 58 with an oppositely extending arm 59 which receives in aslot 60 therein the pin 52. Extendingthrough the shaft member 56 andalso through the hanger 55 is a smaller shaft 61 at Whose endadjacentthe socket member 57 there carried a socket member 62 and at whoseopposite end is a second socketmember 63 with a relatively similarlydirected operating arm 64 which receives in'a 'slot 65 therein the pin53. Adapted to cooperate with the socket members 57 and 58 and 62 and63, re SPOCtlVGlY, are manual control levers 67 and 68 which, as will beapparent from Figure 1, are so shaped that they approach each other attheirupper ends when in sockets 58 and 63 whereby they may be readilygrasped by the operator with the use of only one hand, while by reasonof the parallel disposition of the sockets 57 and 62 they canbesimilarly grasped when in the latter sockets. I

From the foregoing description the mode of operation of my improvedmechanism will be readily apparent. It will be remembered that the motor5 is reversible, Accordingly, as the motor 5 is driven in one (directionand the cam members 44 and 45 are moved to cause the clutch bands 41 totighten upon the braking surfaces 39, both channeling mechanisms Wlll beraised or lowered simultaneously. If one of the levers 67 or 68 isoperated to move its corresponding clutch operating-caimbut one of thechanneling mechanisms will. be moved.

;It will therefore be apparent that by manipulation of the levers 67 and68 and the control mechanism for the motor 5, the channellng mechanismscan be simultane- .ously raised, simultaneously lowered, or

moved independently of each other in either direction. By reason of thefactthat the handles whether in the sockets 58 and 63 or 57 and 62 areso close as to be readily grasped simultaneously by the operator whenusing but one hand, it will be apparcut that, should it become desirablein an emergency to move the two devices in either direction veryquickly, this can be done with ease and certainty. \Vhile I have in thisapplication specifically-described one form which my invcn-' tron mayassume in practice, 1t will be unchanneling devices adjustably mountedon said standards and each having usual channeling steels, and means foradjusting said channeling devices in a direction longitudinally of saidsteels including control levers separately or simultaneously operable bya single hand of the operator.
